Typical Chinese supplier geography

Major Chinese capacity sits in Jiangxi, Guangxi, Guangdong. Coastal producers (Shandong, Jiangsu, Zhejiang) typically dominate export volume because of port access; inland producers (Inner Mongolia, Xinjiang, Shaanxi) compete on raw-material cost but add inland-rail or trucking cost to reach the coast.
